Washington, November 15 Singer Christina Aguilera has revealed that she likes working late at night, but has been finding it difficult to do so after becoming a mother.

The 'Dirrty' hitmaker has a 21-month-old son Max with her music executive husband Jordan Bratman.

"When the sun goes down my whole body starts to come alive, although I am a little different now because I do have a child and my hours have been turned upside down for him," Contactmusic quoted her as saying.

She added: "But I'm still naturally a night owl. If it were up to me my favourite time to work would be between three to four a.m., which is what it used to be before my baby was born.

"Now I'm a mother, I am getting up earlier. It's 6am every day but I'm a night owl regardless, which means that, for me, going to bed early means trying to get to sleep by 12.30am." (ANI)
